MP-1-R 20.000000

Overview

The MtronPTI MP-1-R 20.000000 is a fundamental mode crystal resonator operating at a nominal frequency of 20 MHz. It features a frequency tolerance of ±30 ppm and a load capacitance of 18 pF. The component exhibits an equivalent series resistance (ESR) of 25 Ohms and operates within a temperature range of -10°C to +70°C. It utilizes the HC-49/U package style, providing a standard form factor for through-hole mounting in electronic circuits requiring precise clock signals.

Feature Summary

• Fundamental mode crystal operation for stable frequency generation
• Standard HC-49/U package configuration for reliable mounting
• Defined load capacitance and low ESR characteristics

Applications

• Microcontroller clock sources
• Digital logic timing references
• Communication interface synchronization

Procurement Notes

Verify the specific suffix requirements against your schematic design. Confirm that the ±30 ppm tolerance meets your system's jitter budget. Ensure the HC-49/U footprint matches your PCB layout constraints. Check datasheet specifications for drive level sensitivity to prevent overdriving the crystal element during operation.

Selection Notes

Select this component when a 20 MHz reference with ±30 ppm stability is required. Consider the HC-49/U package size for mechanical clearance. Evaluate the -10°C to +70°C operating range against your environmental conditions. Compare ESR values if impedance matching is critical for your oscillator circuit design.
